A molar pregnancy may seem like a normal pregnancy at first, but most molar pregnancies cause specific signs and symptoms, including:

  • Dark brown to bright red vaginal bleeding during the first trimester
  • Severe nausea and vomiting
  • Sometimes vaginal passage of grape-like cysts
  • Rarely pelvic pressure or pain

If you experience any signs or symptoms of a molar pregnancy, consult your doctor or pregnancy care provider. He or she may detect other signs of a molar pregnancy, such as:

  • Rapid uterine growth — the uterus is too large for the stage of pregnancy
  • High blood pressure
  • Preeclampsia — a condition that causes high blood pressure and protein in the urine after 20 weeks of pregnancy
  • Ovarian cysts
  • Anemia
  • Overactive thyroid (hyperthyroidism)
